  • Hepatitis C virus liposome vaccine
    Patent number: 9814785
    Abstract: The invention provides a method for the prophylaxis or treatment of hepatitis C in a mammal with a peptide-bound liposome wherein the peptide contains a partial amino acid sequence having a length of not less than 9 amino acids in the amino acid sequence of hepatitis C virus NS3 protein, has a length of 9 to 11 amino acids, and is capable of inducing cytotoxic T lymphocytes; the liposome contains a phospholipid containing an acyl group having 14 to 24 carbon atoms and one unsaturated bond or a hydrocarbon group having 14 to 24 carbon atoms and one unsaturated bond, and a liposome stabilizer; and the peptide is bound to the surface of the liposome. The invention also provides a cytotoxic T lymphocyte activator containing the peptide-bound liposome, as well as a hepatitis C virus vaccine.
